Synthesis of Diazo-Bridged BODIPY Dimer and Tetramer by Oxidative Coupling of β-Amino-Substituted BODIPYs

Abstract

A diazo-bridged BODIPY dimer and tetramer were prepared by the oxidative coupling reaction of β-amino-substituted BODIPYs. The structure of the dimer was elucidated by X-ray diffraction analysis, showing its coplanar orientation of two BODIPY units. Effective extension of π-conjugation was confirmed by optical and electrochemical investigations.
